There are two good reasons to want an integrated iPad as standard equipment in your car. The first: so that you can get stuff done while someone else drives you through traffic. The second: to keep your kids amused with their nine-thousandth viewing of "The Croods" on Netflix. A possible third, and equally important, reason might be so everyone in your family can play Candy Crush at a moment's notice. Bentley and Ferrari are swank enough to offer iPads as part of the rear-seat entertainment system, though Ferrari skimps with iPad minis in the rear seats of the LaFerrari. Maybe there isn't room for a full iPad back there?
